The wedge block 6 is allowed to slide on the inner wall of the disc 3. The inner wall of the clamp block 4 is fixedly connected with a guide tube 7. The guide tube 7 can prevent the reset spring 5 from being compressed to a certain extent and causing a large deformation. The outer wall of the machine table 1 is fixedly connected with a support platform 8. The support platform 8 mainly supports and connects the existing hydraulic cylinder 9 and the stamping die 10. A hydraulic cylinder 9 is arranged at the bottom end of the support platform 8. The hydraulic cylinder 9 is an actuator in a hydraulic system, usually composed of a piston, a cylinder barrel and a seal, and is used to convert hydraulic energy into mechanical movement. In a stamping machine, the hydraulic cylinder 9 is usually used to provide pressure to push the punch or die to perform a stamping operation. This is the prior art and will not be described in detail. The movable end of the hydraulic cylinder 9 is fixedly connected with the stamping die 10, and a contact mechanism is arranged on the outer wall of the stamping die 10.

[0031] Reference Figure 1 and Figure 4The inner wall of the support platform 8 is penetrated and provided with a dust gun 12, which corresponds to the circular positioning groove of the disc 3. During the stamping process, the dust impurities during stamping can be sucked into the recovery box 13. The right end of the dust gun 12 is fixedly connected to the recovery box 13, and the inner wall of the recovery box 13 is plugged with a collection frame 14, which can accumulate dust impurities in the collection frame 14, which can facilitate the subsequent centralized treatment of dust impurities. The inner wall of the left end of the collection frame 14 is elastically connected to a slider 16 through a positioning spring 15, and the left end of the slider 16 is fixedly connected to a handle 17, through which the collection frame 14 can be moved out of the recovery box 13 for cleaning, and the inner wall of the left end of the collection frame 14 and the positioning spring One end of 15 is fixedly connected, and when the slider 16 moves to the left, the positioning spring 15 will be compressed. When resetting, the elastic force of the positioning spring 15 is used to reset the slider 16. The other end of the positioning spring 15 is fixedly connected to the outer wall of the slider 16, and the slider 16 is slidably connected to the inner wall of the collection frame 14. The left end side wall of the recycling box 13 is fixedly connected to the outer wall of the support platform 8, and the right end of the handle 17 is plugged into the outer wall of the recycling box 13. The outer wall of the recycling box 13 has a raised part, and there is a round hole on the raised part. The round tube at the right end of the handle 17 can allow the handle 17 to be plugged into the middle part of its raised part to limit the entire collection frame 14, and the handle 17 is slidably connected to the outer wall of the recycling box 13.

[0032] Reference Figure 1-Figure 3 The inner wall of the right end of the clamping block 4 is fixedly connected to one end of the return spring 5. When the wedge block 6 moves to the right, the return spring 5 will be compressed. When resetting, the elastic force of the return spring 5 brings the wedge block 6 to reset. The other end of the return spring 5 is fixedly connected to the right end of the wedge block 6. The wedge block 6 penetrates and is slidably connected to the inner wall of the disc 3. The disc 3 is provided with a notch corresponding to the wedge block 6, which can allow it to move laterally along the inner wall. The wedge block 6 is slidably connected to the outer wall of the guide tube 7. The contact mechanism includes a connecting rod 11, which is fixedly connected to the outer wall of the stamping die 10. The connecting rod 11 contacts the top of the wedge block 6, and the connecting rod 11 is plugged into the top of the disc 3. The disc 3 is provided with a notch for the connecting rod 11. Through the driving rotation in the machine table 1, the notch on each group of workstations of the disc 3 can be accurately plugged into the connecting rod 11.

[0033] Working principle: First, when stamping the automobile metal parts, just place the automobile metal parts in the circular positioning groove of the disc 3, then start the driving mechanism in the machine 1 to make it rotate with the rotating shaft 2 and the disc 3, then start the hydraulic cylinder 9 to let the output end of the hydraulic cylinder 9 move downward with the stamping die 10 and the connecting rod 11. Before the stamping die 10 contacts the automobile metal parts, the connecting rod 11 will penetrate into the notch of the disc 3 to contact and squeeze the inclined surface of the wedge block 6, so that the wedge block 6 uses the elasticity of the return spring 5 to move the clamp block 4 to the right. When the clamp block 4 contacts the automobile metal parts, the hydraulic cylinder 9 will continue to move downward with the stamping die 10 and the connecting rod 11 At this time, the connecting rod 11 will continue to squeeze the inclined surface of the wedge block 6, allowing the wedge block 6 to move to the right. Due to the contact between the clamp block 4 and the automobile metal accessories, a reaction force is generated, causing the wedge block 6 to move to the right and compress the return spring 5. The reverse elastic force of the return spring 5 is used to make the clamp block 4 continue to contact and position with the automobile metal accessories, and the clamp block 4 can continue to contact and position until the stamping die 10 and the automobile metal accessories are stamped. After the stamping is completed, the hydraulic cylinder 9 is allowed to bring the stamping die 10 and the connecting rod 11 to reset upward, and the connecting rod 11 is allowed to slowly detach from the notch of the disc 3 without contacting the inclined surface of the wedge block 6, which will allow the reverse elastic force of the return spring 5 to bring the wedge block 6 and the clamp block 4 to reset to the left, completing the automatic stamping positioning process.

[0034] During the stamping process, the vacuum gun 12 is started to allow the vacuum gun 12 to suck the dust and impurities generated by the stamping into the collection frame 14 for collection. When the collection frame 14 needs to be replaced, the handle 17 and the slider 16 need only be moved to the left to separate the round tube from the raised circular hole of the recycling box 13. At this time, the positioning spring 15 is in a compressed state, and then the collection frame 14 is pulled outward to separate from the recycling box 13. During installation, the handle 17 and the round tube need only be moved to the left, and then the collection frame 14 is plugged into the inner wall of the recycling box 13. When the round tube of the handle 17 coincides with the raised circular hole of the recycling box 13, the handle 17 is released and the reverse elastic force of the positioning spring 15 is used to reset the handle 17 and the round tube, and the round tube and the raised circular hole of the recycling box 13 are plugged into each other to limit the entire collection frame 14.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
